A limit switch turns on or off when the object being sensed reaches a specific location.

A proximity sensor returns an analog signal indicating how far the object is from the sensor.

What is the difference between npn and pnp proximity sensors?

No worries. The important thing here is that this module is simply reading a voltage from the sensor with reference to the ground of that sensor. This means that this module is always going to be a sinking device, and will be always be sinking small amounts of current from that sensor. This means, that your sensor is going to be powered externally and we will simply be reading the output voltage from it. Here is a link to a knowledgebase article about sinking and sourcing current. I hope this helps to clarify.


What signal is generated by a hall sensor?

A: DISTURB signal when the magnetics are in proximity


What are the advantages and disadvantages of inductive proximity sensor?

The advantages of inductive proximity sensors areThey are very accurate compared to other technologiesHave high switching rateCan work in harsh environmental conditionThe disadvantages of inductive proximity sensor areIt can detect only metallic targetsOperating range may be limited


Is the only difference between a front and rear oxygen sensor the length of the wire or are the sensors themselfx different?

i asked one of the technicians at autoparts warehouse.com this same question cuz i was wondering about my 99 Honda prelude. They said the wire is the only difference. Im pretty sure the rear sensor has a shorter wire.


What are the main difference between the sensor less induction motor and induction motor?

basically sensorless scheme estimated the speed using current signal or current sensor without considerartion speed sensor thats reduce the cost of machine and make it more efficient ..basically sensorless scheme can uses sensor only at current signal or sensor at dc link in doubly fed machine,.........................
